Elvis, is it possible that the clutch basket nut had become loose? Just a thought, but this could have led to the gear becoming partially disengaged causing a massive side load on it as it got jammed by the driven gear on the oil pump. That certainly could have snapped the gear in half. Have you checked the oil pump to make sure it rotates freely? Usually not a lot of torque required to spin an oil pump up to pressure. I'm just trying to see if there may have been another cause for the gear to have experienced that much load to break it in half.

BTW, I agree with jhalfhide that the SMT can be just as spirited a ride as the Superdukes. I own both an SMT and an SDR and the SMT can definitely be ridden just as fast or faster in some situations. Love them both.

The clutch nut took me 5 minutes to temove with impact driller so it was very tight, just for comparison the front sprocket nut with same driller took me 5 seconds to remove.
The pump is rotating freely with out the pump cover and have small friction with the new cover but still can turn with my fingers, during turning i can hear suction noise made with the leftovers of oil.

I can not find any damage that was caused not from the oil pump sprocket but it is also a question how well the axel of the clutch basket is balanced but this i can not test

Yeah I agree. Nothing wrong with the SM frame, but the SD site seems (seemed ?) to have a different demography, I would guess in their 20's ?, where as this site seems to have older riders (40-50's ?). Younger riders ride their bikes harder in my experience. That's all I was getting at. I could be completely wrong with my age judgement ! (I'm 46)

Elvis, thanks for the extra info on the clutch basket. I guess that rules out that theory. Your observation on the revised drive gear is looking more like the correct conclusion. Weak part - Update with strong part...Deny everything.

To the other part of my post: 65 here and riding harder and better than ever. I have only had the SMT for a couple months now, but am amazed at how well it handles being ridden fast. I did machine some handlebar mounts that move the bars forward to the "proper" position, which made the handling more like what I am used to. After my first outing I had scrubbed the front tire to the edge for the first time on any bike I have owned. So well balanced, front to rear evenly weighted on the tires. Not front end dominant like most "performance" bikes.

Good on you both for going hard . When I came on this site, I noticed a lot of SMT riders with that "fuely" app screenshot in their signature block and many talked about fuel economy and touring on the bikes. That sort of set the bad stereotype. Perhaps they have moved on to BMWs or Goldwings now ?

I've been thinking about what you said for a few days now. The thought keeps on returning. The SMT is possibly the easiest bike to wheelie (other than small dirtbikes). You pop it up and sits level and straight. I used to own a 06 990 SD and with the EOM exhaust removed and the titanium can puts on. The 20 kg difference ruined the bike's balance (I'm a small bloke) and as you said, made the centre of gravity too far forward. Wheeling was difficult to keep straight. I nearly ran into a parked car once. I didn't do much wheelie'ing on the SD.

Last update from KTM, they wrote me that the change in oil pump gear is due to supplier change and nothing to do to part faulty design.
They also wrote that since they do not have a record of my bike getting oil change at the KTM dealer in the last 2 years they put it down as wrong oil and filter used.

I did found this issue in the RC8 forum and one guy wrote the following:
The oil pump gear had been known to shatter, which means no oil fir the top end. Surprised though, since yours is a 2013 with the upgraded solid gear

How did you remove the 130Nm clutch bolt ?. Did you use a shaft lock bolt ?

Cheers J

To open i just stuffed some rags in the place the clutch discs goes in to make some friction, put it in neutral
and let the impact driller do the job, when the the impact started to rotate freely with the nut i just stop and push the rags in again, after several times like this it came of but please note also when the nut was 1 mm out the nut was still hard to get out.

to torque back i used this with the support of the foot peg on the handle.
